ERF(ll,ul)


  • is the lower limit and is the upper limit.


Description

  • This function gives the value of the error function .
  • Error function is the special function which is encountered in integrating the normal distribution.
  • In is the lower limit of the integrating function and is the upper limit of the integrating function.
  • Also is optional. When we are omitting the value, then the integral of the error function between 0 and the given value is returned otherwise it will consider the given and values.
  • This function is also called Gauss error function.
  • is defined by:
  • .
  • In this case 'a' is the lower limit and 'b' is the upper limit.
  • This function will return the result as error when
  1. any one of the argument is nonnumeric.
  2. ll or ul is negative.


Examples

  1. ERF(1,2)=0.15262153
  2. ERF(3,2)=-0.004655645
  3. ERF(0,1)=0.842700735
  4. ERF(5)=1
  5. ERF(-3)=NAN
